Specification forming part ofLetters Patent No. 30,645, dated November 13, 1860.

To all whom it may concern: v

Be it known that I, GEORGE S. RoUDEBUsH, of Natchez, in the county of Adams and State of Mississippi, have .invented a new and Improved Machine for Cutting Standing Cotton and Corn Stalks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the annexed drawings, making a part of this specification, in which-- Figure l'is a side sectional view of my invention, taken in theline a to, Fig. 2; Fig. 2, a plan or top view of same.

Similar letters of reference indicate corresponding parts in the several figures.

This invention is designed for cutting into pieces standing cotton and corn stalks, so that the same may be plowed under the surface of the ground and the latter rendered suitable for cultivation at a very moderate expense, the hitherto-tedious hand-labor being avoided, and the work done much more thoroughly.

Theinvention consists in the employment or use of a biconieal roller, provided withflanges and cutters, and used in connection with stationary scrappers anda rotating cutting-cylinder, all the parts being placed in a suitable frame and arranged for joint operation, as hereinafter shown, to effect the desired end.

To make those skilled in the art to fully understand and construct my invention, 1 will proceed to describe it.

A represents aframe, the back partof which is provided with handles B B. The frontpart of the frame has a sbaft,O,flttcd transversely in it, and on this shaft a biconieal roller, D, is placed loosely. This roller D is formed of two equal parts, a a, frustums of cones, the smaller diameters of which adjoin each other. (See Fig. 2.)

Each part c of the roller is provided with four circumferential flanges, I) b b b. The flanges b are at the outer parts of the roller, and the flanges b at the inner part. The latter flanges have knives E bolted to them, said knives extending entirely around the flanges b. The flanges b are designed to support the front part of the frame when the machine is I running or passing over solid ground on roads in being drawn from place to place.

In the frame A, just back of the roller D, there is secured a traversebar, F, to which teeth or bars G are secured at right angles.

These teeth or bars G extend forward by the sides of the flanges b and knives E, as shown clearly in Fig. 2. In the frame A, 'ust behind the bar F, there is a cylinder, H. This cylinder is formed of two heads,'c c, placed on a shaft, (1, said shaft being fitted in bearings c at the under side of'the frame. The heads 0 c are connected at their peripheries by slats f, which are placed at equal distances apart, and are grooved at one side to receive knives g, which are bolted to the slats. The back part of the frame A is supported by a caster-wheel,

I, when the machine is being drawn from place The biconieal form of the roller admits of i it conforming to the ridges in which the plants are grown. The bars G serve as scrapers to keep the knives E and flanges b clean. The roller Dis made of two parts to facilitate the turning of the machine.

Havingthus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is p The biconieal roller D, provided with the knives E, in connection with the knife-cylinder H, and with or without the bars or scrapers G, all being placed in the frame A, essentially as and for the purpose set forth.
